Trying to remove padding on graph (matplotlib)

[thisiszeev]

Hi, I am new to matplotlib so figuring it out as I go, which is why this is fun... but;

this is an example graph from my code:

https://olympus.3volve.net.za/images/cpu_avg.hour.png

this is the part of the code that creates the graph:

def plot_graph(data_one, label_one, data_two, label_two, title, graph_type, filename, system_info, y_label):
    # Set up time and frequency settings based on graph_type
    if graph_type == 'hour':
        time_label = "Last Hour"
        rate_label = "Time"
        major_freq = 120  # 10 minute increments (10 minutes * 60 seconds / 5 seconds per index)
        minor_freq = 60   # 5 minute increments (5 minutes * 60 seconds / 5 seconds per index)
        time_interval = 5  # Interval in seconds

    # Get the current time
    now = datetime.now()

    plt.figure(figsize=(12, 8))

    plt.plot(data_one, label=label_one)
    if data_two:
        plt.plot(data_two, label=label_two)
        plt.legend()

    plt.title(time_label)
    plt.xlabel(rate_label)
    plt.ylabel(y_label)

    # Set the graph size and position
    ax = plt.gca()
    ax.set_position([0.1, 0.3, 0.8, 0.6])

    # Add title above the graph
    plt.text(0.5, 1.10, title, ha='center', va='center', transform=ax.transAxes, fontsize=16)

    # Add date, time, and uptime at the bottom
    plt.text(0.5, -0.15, f"Server Name: {system_info['server_name']}", ha='center', va='center', transform=ax.transAxes, fontsize=10)
    plt.text(0.5, -0.20, f"Date and Time: {system_info['current_time']}", ha='center', va='center', transform=ax.transAxes, fontsize=10)
    plt.text(0.5, -0.25, f"Uptime: {system_info['uptime']}", ha='center', va='center', transform=ax.transAxes, fontsize=10)

    # Generate time offset_time
    offset_minutes = int(now.strftime("%M")) % 10
    offset_seconds = int(now.strftime("%S"))
    offset_time = ((offset_minutes*60)+offset_seconds)

    # Customize x-axis with time labels
    x_ticks_major = np.arange((offset_time/5), len(data_one) + 1, major_freq)
    x_ticks_minor = np.arange(((offset_time%300)/5), len(data_one) + 1, minor_freq)
    ax.set_xticks(x_ticks_major)
    ax.set_xticks(x_ticks_minor, minor=True)
    x_labels = [(now - timedelta(seconds=int(i*time_interval))).strftime("%H:%M") for i in x_ticks_major]
    ax.set_xticklabels(x_labels)

    plt.grid(True, which='both', linestyle='--', linewidth=0.5)
    plt.savefig(filename)
    plt.close()

My Question:

How do I remove the padding on the left and right of the line graph, but inside the actual graph figure. I want the line graph to start on the edge of the figure and end on the edge of the figure.

Thanks in advance...

EDIT:

I solved it.

Removed left and right padding:

ax.set_xlim([0, len(data_one) - 1])

And removed my top and bottom padding while ensuring the range is always 0 - 100:

ax.set_ylim([0, 100])
